IMPROVEMENT IN STRAW-CUTTER.

The Schedule referred to in these Let-ters Patent and makng partici the same.

l I, HARRISON OGBORN, of Richmond, in the county of Wayne and State oflndana, have invented certain Improvements in Straw and Fodder-Cutters, of which the following is a specification.

The nature of my invention consists in making a `double-edge reversible knife, and providing it with two `sets of holes, to allow either edge to beuscdjas may may be required; also, in devices for attachingthe .arm that holds it to the face-plate, together with the adjustable plate that holds itin position. `V "L Figure 1 is a perspective view of a machineembody 'Figure 2 is Pan elevation of `the machine from the front.

Figure 3 is a vertical section of the arm, handle,

and double-edged knife.

G G G is the frame of theimaehine, which should be strongly made, to resist the jarring strain produced bytheeutting process. p y

Ais the arm that holds the knife B in its proper. position.

N N are 'screws or bolts thatholdthe knife to the C is a handle, by means of which the'parm A and 'knife Bfare made to rotate upon-the pin L', 4which arm l and knife are held iii-place on said pin by'nnt I.

The other end of. the arm `comes inside f the part O of the adjustable plate D, and is thus held close to the face-plate, and prevented `from springing away from the face-plate, as shown in fig. 1.

When it is desired to reverse the knife and use the convex edge, it is only necessary to take the arm and knife off ofthe machine and pnt the handle on the other end and the pin L through the hole where the handle is attached in fig. 1, and move the screws N N into dotted holes in the knife nearest the concave edge, and the machine will be as represented in iig. 2.

The handle C has a flange, P, which protects the hand against accidental contact with flange O. Thus it will` be seen that either edge of the knife may be used.A

1. The reversible arm A and adjustabledoubleedged knife B, when made in the manner substantially as described, and used for the purposes indicated.-

2. The reversible arm A and adjustable doublcedged knife B, in combination with the flange P and guide-plate O D, when constructed and operated for the purpose and in the manner set forth.
